DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 illustrates one implementation of a communication system 100. Thecommunication system 100 includes a hand-held, wireless mobilecommunication device 102 a point-of-sale device 104 and a managementserver 106. In one implementation, the mobile communication device 102includes a mobile application (discussed in greater detail below) thatpermits a user of the mobile communication device 102 to conduct paymenttransactions. Payment transactions can include, for example, usingcontactless payment technology at a retail merchant point of sale (e.g.,through point of sale device 104), using mobile/internet commerce (e.g.,purchase tickets and products, etc.), storage of payment information andother digital artifacts (e.g., receipts, tickets, coupons, etc.),storage of banking information (payment account numbers, security codes,PIN's, etc.), and accessing banking service (account balance, paymenthistory, bill pay, fund transfer, etc.), and so on. The mobilecommunication device 102 can be a cellular phone, a wireless personaldigital assistant (PDA), a laptop computer, or other wirelesscommunication device. The point of sale device 104 can be a desktopcomputer, laptop computer, terminal, or other device that is configuredto receive user input selecting items for purchase or other transaction.

In one implementation, authorizations for payment transactions that aremade through the point of sale device 104 are sent from the point ofsale device 104 to an issuer authorization (e.g., management server 106)through the mobile communication device 102 (as shown in FIG. 1). In oneimplementation, an issuer authorization is a payment entity that eitherapproves or disapproves a payment transaction. An issuer authorizationcan be, e.g., a person, computer system, bank (or other third party).One potential benefit of having payment authorizations flow through themobile communication device 102 is that sensitive user information (e.g.account numbers, pin numbers, and/or identity information) need only besent from the mobile communication device 102 directly to an issuerauthorization. Such operation reduces the potential for identity theftand/or fraudulent purchases made through a point of sale device. Forexample, (in one implementation) payment authorizations cannot be sentto an issuer authorization if the mobile communication device 102 isturned off.

FIG. 2 illustrates one implementation of the mobile communication device102. The mobile communication device 102 includes a mobile application200 that (in one implementation) is provided to the mobile communicationdevice 102 through a remote server (e.g., management server 106). In oneimplementation, the mobile application is a Mobile Wallet applicationavailable from Mobile Candy Dish, Inc., of Alameda, Calif. In oneimplementation, the mobile application is a hosted service, as describedin U.S. patent application Ser. No. 11/939,821, entitled “Method andSystem For Securing Transactions Made Through a Mobile CommunicationDevice”, which is incorporated herein by reference. In oneimplementation, the mobile application 200 is configured to sendrequests to the management server for artifacts based on user input,e.g., received through a keypad (not shown) of the mobile communicationdevice 102. Requests to the management server 106 can also be automated,via proximity-based services, e.g., consumer tapping (or in closeproximity) an LBS/contactless/RFID enabled phone against a smart poster(RFID/Bluetooth/LBS enabled, etc.), kiosk, or other device.

In one implementation, the mobile application 200 running on the mobilecommunication device 102 is configured to receive artifacts (e.g.,advertisements, receipts, tickets, coupons, media, content, and so on)from the management server 106. In one implementation, the managementserver 106 sends artifacts to the mobile application based on userprofile information and/or a transaction history (or payment trends)associated with a user of the mobile communication device 102 asdescribed in U.S. patent application Ser. No. 11/944,267, entitled“Method and System For Delivering Information To a Mobile CommunicationDevice Based On Consumer Transactions”, which is incorporated herein byreference.

In one implementation, the mobile communication device 102 is anNFC-enabled phone. The mobile communication device 102 can beNFC-enabled, for example, through an embedded chip or a sticker that isaffixed to the cellular phone, as described in U.S. application Ser. No.11/933,321, entitled “Method and System For Adapting a Wireless MobileCommunication Device For Wireless Transactions”, which is incorporatedherein by reference. In one implementation, the NFC chip (or sticker) onthe cellular phone can be used in conjunction with a merchant's point ofsale device as described in greater detail below.

For example, with reference to FIG. 4, in one implementation, the NFCchip (or sticker) on the cellular phone can communicate with NFC chipsthat are installed on the front of PC's (TV's, Kiosks, or any otherdevice) and serve as scanners/readers. In this implementation a mobilecandy dish applet (e.g., MCD POS plugin 414) is installed on theconsumer's computer (e.g., PC 404) which interfaces with the NFC chip onthe PC. When a consumer (or user) is shopping online and they are readyto pay for their products, the consumer opens his mobile wallet andselects one of the payment methods (e.g., credit card, debit card,prepaid card, etc.) from their mobile wallet. If a default card has beenselected already, this step is not necessary. The consumer then wavestheir phone over the NFC reader present on the PC 404. The consumer'spayment credentials are transferred from the phone to the merchantwebsite (e.g., online store application 410) using a communicationprotocol between the chip in the phone and the chip in the PC, which canbe radio frequency for example. If the consumer has coupons in theirmobile wallet the consumer can either elect to manually apply thecoupon, save the coupon for a future use (against a larger purchase forexample), or have the coupon automatically applied during thetransaction and the transaction amount is updated. After the consumerenters any necessary validation information (e.g., pin) to provide amulti-factor authentication and confirms the transaction, the onlinepurchase is processed as normal by the merchant's online processor. Themobile wallet can retrieve transaction data, account balance from themanagement server 408.

In one implementation, the mobile communication device 102 is a nonNFC-enabled phone. In this implementation, the consumer connects hisphone to the PC 404 via some non radio frequency method (e.g., IR,Bluetooth, USB cable, etc.). When a consumer is shopping online and theyare ready to pay for their products, the consumer opens his mobilewallet and selects one of the payment methods (e.g., credit card, debitcard, prepaid card, etc.) from their mobile wallet. If a default cardhas been selected already, this step is not necessary. The consumer thenpushes, e.g., a “Buy now” button and the consumer's payment credentialsare transferred from the phone to the merchant website (e.g., onlinestore application 410) using the protocol between the phone and the PC404 which can be radio frequency, for example. If the consumer hascoupons in their mobile wallet the consumer can either elect to manuallyapply the coupon, save the coupon for a future use, or have the couponautomatically applied during the transaction and the transaction amountis updated. After the consumer enters any necessary validationinformation (e.g., pin) to provide multi-factor authentication andconfirms the transaction, the online purchase is processed as normal bythe merchant's online processor. The mobile wallet can retrievetransaction data and account balance from the management server 408.

In one implementation, the management server 408 and merchant portal(e.g., online store 408) are maintained by trusted parties and use anencrypted tunnel to transfer financial data. When the consumer is readyto pay for their online product, they enter their cell phone number onthe merchant portal. The merchant portal (which has an MCD applet (e.g.,MCD POS plugin 414) installed on its server) securely connects to themanagement server 408 (that in one implementation is maintained byMobile Candy Dish (MCD)). In one implementation, the management server408 identifies the consumer through their cell phone number, andverifies the consumer's authenticity by sending a unique transactioncode to the consumer mobile wallet on their cell phone. The consumerthen enters this unique transaction code onto the merchant's web portal.The merchant portal sends this transaction number to the managementserver 408 for authentication. Upon authentication, the consumer'svirtual wallet and payment methods (e.g., credit card, debit card,prepaid card, etc.) are securely retrieved from the management server408 and are displayed to the consumer in a window on a websiteassociated with the merchant portal. The consumer selects one of thesepayment methods to pay for their transaction. If a default card has beenselected already, this step is not necessary. If the consumer hascoupons in their mobile wallet the consumer can either elect to manuallyapply the coupon, save the coupon for a future use, or have the couponautomatically applied during the transaction and the transaction amountis updated. After the consumer enters any necessary validationinformation to provide a multi-factor authentication and confirms thetransaction, the online purchase is processed as normal by themerchant's online processor. The mobile wallet can retrieve transactiondata, account balance from the management server 408.

Referring to FIG. 2, in one implementation, the mobile application 200maintains a shopping list 202 for a consumer. Accordingly, consumershave the ability to store their shopping list in their mobile wallet andadd, delete, or change items on their shopping list either in offline oronline mode. In one implementation, consumers are sent coupons based onitems on their shopping list, preferences, previous shopping history,proximity to the physical retail store, or a combination of theseparameters, as discussed in application Ser. No. 11/944,267, which isincorporated by reference above. If the consumer has coupons in theirmobile wallet the consumer can either elect to manually apply thecoupon, save the coupon for a future use, or have the couponautomatically applied during the transaction and the transaction amountis updated. When a consumer wants to order the items on their shoppinglist via an on online merchant (in contrast to a physical retail store),the consumer can logon to the merchant portal and electronicallytransmit their shopping list to the merchant portal either by wavingtheir phone over NFC enabled PC's or some other connection such as IR,bluetooth, USB, or the like.

FIG. 3 illustrates a method 300 for conducting a payment transactionusing a point of sale device (e.g., point of sale device 104). Userinput is received selecting one or more items for purchase (e.g., at thepoint of sale device) (step 302). In general, the transaction being madeat the point of sale device can be any type of transaction that involvesthe exchange or transfer of funds—e.g., the transaction can be a paymenttransaction, a fund transfer, or other type of transaction. In responseto a request from the user to purchase the one or more items, a totalpurchase amount for the one or more items is calculated (e.g., by thepoint of sale device) (step 304). If the user has coupons in theirmobile wallet the user can either manually apply the coupon or have thecoupon automatically applied during the transaction and the transactionamount is updated. The user request to purchase an item can be received,e.g., by a user clicking on a “buy now” icon that is displayed on agraphical user interface of the point of sale device. Paymentauthorization for the total purchase amount is sent to a payment entitythrough a mobile communication device of the user (step 306). A resultof the payment authorization is received at the point of sale devicefrom the payment entity via the mobile communication device (step 308).The payment transaction is completed based on the result of the paymentauthorization (step 310). If the payment transaction was authorized bythe payment entity, then the sale of the items through the point of saledevice is completed. Otherwise, if the payment transaction was notauthorized by the payment entity, then the point of sale deviceterminates the payment transaction.

FIG. 4 illustrates an example payment transaction being made in acommunication system 400 in accordance with one implementation. Thecommunication system 400 includes a mobile communication device 402, apersonal computer (PC) 404, an online store 406, and a core (ordatastore) 408. As indicated by interaction (1), a user (or customer),using a phone (e.g., mobile communication device 402 or personalcomputer 404), browses an online store website (online store application410) and finds an item that the customer wishes to purchase. This couldalso be a purchase made through a midlet application (POS midlet 412)residing on the mobile communication device 402. The user then goes to,e.g., a checkout of the online store 406 make a purchase. If the userhas coupons in their mobile wallet the user can either manually applythe coupon or have the coupon automatically applied during thetransaction and the transaction amount is updated. When it comes time toauthorize the purchase, (in one implementation) the user is given anoption to purchase with the mobile communication device 402. In oneimplementation, the mobile communication device 402 is an NFC-equippedphone (or NFC phone).

In interaction (2), when the user chooses to purchase with the mobilecommunication device 402, the online store application 410 sends thetransaction information for authorization to the POS vendor plugin(e.g., MCD POS plugin 414). In one implementation, the POS vendor pluginis installed in the merchant's online store and enables the merchant toaccepts MCD Blaze payments as an alternative form of payment, similar toaccepting credit cards for payment. As shown by interaction (3), the POSvendor plugin formats, encrypts, and cryptographically signs thepurchase authorization request which is sent via a secure SSL link(e.g., HTTPS, Bluetooth, IR, USB, or other suitable protocol)established by the browser/web application 416 back to the mobilecommunication device 402. As with the first scenario, all communicationsis over secure channels. (It may be required that the mobile walletapplication be opened prior to beginning a phone online purchase.) ThePOS midlet 412 is a component of the mobile wallet application thatexecutes PayPass or other payment authorization protocol between itselfand the SE payment applications on the mobile communication device 402(interaction (4)). The results of the request are sent back to the POSvendor plugin.

As shown by interaction (5), the POS midlet 412 then forwards theproperly formatted authorization request to a payment entity (e.g.,issuer authorization 418) for authorization. The results of the requestare then sent back to the POS component of the mobile wallet. Throughinteraction (6), the POS midlet 412 then forwards the results back tothe MCD POS plugin 414 to complete the purchase. The MCD POS plugin 414then forwards the purchase transaction information to the managementserver 408 for later customer viewing (interaction (7)). As indicated byinteraction (8), users (or customers) will then be able to query themanagement server 408 and immediately obtain purchase information,either by phone or PC.
